    Comment:
test3.zip (attached) includes a utility program CreateTables.java that creates database tables and data sufficient to reproduce this problem.  (It reads the SQL statements from createTables.sql.)  If this is still 'useless', please let me know what would be useful.  I'm eager to help you reproduce this problem, but I don't have a clear idea what I can do to help.

test3.zip also includes a version of Scan.java that checks for 'lost' members of the Role.associations set.  It finds several:

11:14:43,859 ERROR [com.docent.lms.entities.tests.hibernate.Scan] !Role#8...@10...ntains(RolePermissionAssociation#{Role#8@1045, Permission#48@1046}@1047)
11:14:43,875 ERROR [com.docent.lms.entities.tests.hibernate.Scan] !Role#7...@10...ntains(RolePermissionAssociation#{Role#7@1049, Permission#48@1046}@1050)
11:14:49,281 ERROR [com.docent.lms.entities.tests.hibernate.Scan] !Role#6...@10...ntains(RolePermissionAssociation#{Role#6@1058, Permission#102@1059}@1060)

... which suggests that Hibernate collections are also affected by this problem.
